Application filed March 16, 1912- Serial No. 684,120.

E. WINDER, a citizen of .the United States, residing at VValtham, countyof Middlesex, State of Massachusetts, have invented a new and usefulAutomatic Bottle-Blowing Machine, of which the following is aspecification.

This invention relates to the art of manufacturing glassware, and moreparticularly to the automatic pressing, molding and blowing glassbottles, and has for its object to provide a machine wherein the severalsteps necessary for the formation of a bottle from the gather of glassare performed within the machine entirely automatically, and the onlymanual operation necessary is the placing of the gather of glass withinthe press mold of the machine.

It has for a further object to provide a mechanism for automaticallycutting the gather of glass after it is placed within the press mold,producing a partial vacuum within the press mold sufficient to draw thegather of glass into the mold and form the neck of the bottle, cause theoperation of a mechanism to punch an initial opening inthe neck of theblank and thereafter admitair to give a preliminary blowing to shapetheblank, next automatlcally removing the blank from the press mold andmaintaining it in an inverted position and bringing it in the sameposition into the blow mold.-

where the blowing mechanism operates thereon to form a completed bottleand then providing an ejector mechanism for'successively removing thefinished bottles from the machine.

It has for a further object to provide a novel air valve mechanismwhereby air under pressure is controlled and delivered at predeterminedtimes to the different parts of 'the machine for ,causing the completionof certain steps in the process of formingand blowing the articles.

It further consists of other novel features of construction, all'as willbe ,.hereinaf-ter'i.

fully set forth.

For the purpose of illustrating my inve ns tionji il have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practice to give satisfactory andreliable results, although it is to be under- 6 that the variousinstrumentalities of" .3 invention consists can be variously beingomitted to avoid confusion.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings: 1 designates the base-of a machine formolding and blowing glass bottles and like forms and-carrying thereon acolumn 2 preferably centrally disposed with respect to the base 1, andhaving a flange3, by means of which it is secured by bolts 4 or likefastening devices to the aforesaid base 1. The flange 3 as here shown,is

. provided with a circular groove 5 substan-' tially concentric withrespect to the column 2 and serving the purpose of a ball race in whichare located a plurality of ball-bearings 6, which latter fit into asimilar ball race 7 formed in an annulus 8 fitting around the column 2.This annulus 8 is provided on its outer periphery with worm teeth 9 andis also formed with a beveled countersunk por tion providing a frictionface 10 with which a ring 11, havinga cone face 12 thereon, is adaptedto coact. This ring 11 is secured by means of-k'eys or pins 13 to a hub14 whereby it rotates therewith but may have a sliding movement relativethereto, if desired. It being noted that the two faces 10 and 12 arefrictionfaces, and are firmly held together by means of the spring 15.The function of this construction is to provide a fric tion drive forcertain elements presently to be described, and which are attached tothe hub 14 so that at certain times when the friction 1s overcome, thering 11 will cease to rotate.

The driving mechanism for the annulus 8 comprises, in the presentinstance, a worm 16 fixedly mounted on a shaft 17, the latter havingsintable bearings 18 and carrying thereon a sprocket 19 driven by asprocket chain 20, from a sprocket 21 mounted on the main shaft 22. Theshaft 22 is of course driven from any suitable source of power from thepulley 23 and is adapted to operate continuously.

' 24 designates the press mold table which,

in the present instance, forms an integral part of the hub 14 andcarries thereon a plurality of cylinders 25, fixedly secured thereto bymeans of bolts 26 or the like, which are also secured by similar bolts27 to the blow mold table 28, here shown as located a suitable distanceabove thetable 24. It will thus be apparent that motion transmitted fromthe annulus 8 to the hub 14 will cause both tables to rotate about thecolumn 2. The table 24, in the present instance, is provided with aplurality of openings 29 adapted to receive a tubular member 30 havingasupporting flange 31 thereon by which it is properly suspended from thetable. lower end of this member 30 is closed by a cap 32 into which isthreaded a sleeve 33,

engaged by an exhaust-head, presently to bedescribed, whereby a vacuumis created in the space 36 to cause the desired suction through theports 35 and 37 whereby the gather of glass 40 is drawn into the pressmold.

41 designates a bushing secured to the sleeve 33 and serving to guidethe plunger 42 during the initial step of punching an opening in theneck of-the gather 40. This plunger 42 is slidingly mounted in thesleeve 33 and embodies a piston valve 43 closely fitting the bore of thesleeve 33 and controlling the opening and closing of a port 44 for theadmission of air under pressure. The piston 43 has a stem 45 securedthereto, project- 7 The are normally held retracted as shown in Fig.

20. The operation of the plunger 42 is effected, in the presentinstance, by a cam track or way 48 secured to .the fixed base 1 and inthe path of movement of the head 46.

49 designates a guide plate, fixedly secured to the table 24, having acentral opening 50 to receive the flange 31' of the member.30 and endslots 51, these latter beingalined with openings 52 in the table 24 inorder to permit the studs 53 to pass therethrough and bring the camrollers 54 into operative relation with the cam grooves 55in the disk56. As shown in Fig. 8, each 56 has a cam groove 55 at each end while acentral aperture 57 allows the disk todit over the tubular a the disks56 is to open and close' the press molds 38 at the desired timesan'doscillation of the disks 56 is effected by providing each withprojecting lugs 60 adapted to be engaged by stationary trips 61 at theproper time. Movement of the disks 56 is transmitted to the press molds38 by means of posts 62 mounted on base members 68 and to which thestuds 53 are connected. The posts 62 are slidingly mounted in the guideplates 49 and are connected by links 6 1 with the press mold sections,it being noted that these sections 38 are formed with ears 65pivoted ona spindle .66 which is fixedly secured, in the present instance, to theguide plates t9.

It will be apparent that when the disks 56 are shifted that acorresponding movement of the press molds will take place, they beingeither opened or closed as the case may be. Assuming they have beenclosed about a gather of glass, as shown in Fig. 19, a suction isproduced in the space 36 which through the ports 35 and 37 draws theglass into the mold. lVhile the glass is thus held by suction, theplunger 42 is operated, through the head 46 meeting the cam track 48 anda preliminary opening punched in the glass. On'leaving the cam track 18the plunger 42 is withdrawn and a blowing step takes place whichproduces the effect shown at 07 in Fig. 20.

(i8 designates a frame suitably carried, in the present instance by thebase 1 and carrying a cross head 69 in which is slidingly mounted a cam70, having connection with the piston 71 of a cylinder 72. This cam 70coacts with a roller 73 carried by the latch bar 7 4, the parts beingmaintained in proper engagement through the medium of a spring 75 whichis secured at one end to the bar 74 and at the other end to a fixedportion of the frame 08. This latch bar 74 is normally held engaging oneof the notches 76 formed in the edge of the table 24 and by which thetable is locked after making a partial rotation. The latch bar 74: iswithdrawn from its locking position by a movement of the cam 70 which iseffected by admitting fluid pressure into the cylinder 72 by way of theconduits 77 and 78.

79 designates a three way control, valve for the pressure fluid and theposition thereof controls the flow of pressure fluid to the conduits 77,78 and blow head 101. The operation of the valve 79 is effected by afoot treadle 80 operating through suitable link connections 81 and heldin normal position by means of the spring 82. 1'.t is desirable toprovide a means to lock the treadle 80 for a predetermined time, and forthis purpose Iutilize acatch 83 suitably pivoted adjacent the treadle 80and having a spring 84: connected to a fixed part, as the bracket 85, bywhich the catch 83 is drawn into locking position above the treadle 80when the lathe is depressed. In order to release the catch 83 Ipreferably employ a pin 80 slidingly mounted on the head of cylinder 72and projecting interior thereof so that when the piston T1 descends willstrike the said pin 80 and causethe catch 83 to be swung 65 back,thereby releasing the treadle 80 which is shifted by spring 82 to againoperate the valve 79.

87 designates a-cylinder suitably mounted on the frame 08 and embodyingthe piston 88 and rod 89 which form the operating means for a plate 90slidingly mounted on the table 91 and adapted to be reeiprocated by themovement of the piston 88. The cylinder 87 received pressure fluidthrough the pipes or conduits 92 and 93, the same being respectivelyconnected to the conduits 77 and 78. The plate 90 carries thereon a pairof rollers 94 suitably spaced apart to receive the cutter blades 95which are pivoted at 96 and have end portions formed as wiper cams 97adapted to engage the rollers This movement of the plate in onedirection causes the cutter blades to close while the opposite movementopens them.

It will be noted that these cutter blades 95 are so positioned that whenthe table 24 rotates and brings a press mold adjacent the frame (38, thetop of the said mold will be directly beneath these cutters with themold opening axially alined with the meeting edges of the blades. 1

98 designates a suction head suitably mounted on the frame 08' andadapted to be connected to a pumping element or the like forproducing-the desired vacuum. To the head 98 a lever arm 99 is connectedhavinga slot and pin connection 100 with the latch bar 74 so thatmovement of the latter causes the head 98 to move toward or away fromthe tubular member 30. When the head 98 is moved to engage the member30, it alines with the port 89 and thus produces the desired vacuum fordrawing the gather of glass into the press mold.

101 designates a blow head suitably secured to a link 102 which ispivoted on a bracket 103, and operated by a fluid motor 104. Air issupplied to the head 101 through the conduit 105 and the parts are sopositioned and controlled as to come into opera tion just after theglass in the press mold has received the initial punching by plunger 42.Thus the gather of glass will be inserted, cut and punched at station AFig. 12 and then the latch bar 74: will be withdrawn permitting thetable 24 to move, say one-eighth of a revolution, to station B.

At this station the blow head 101 is brought the respective moldsections.

posed on the table in a corresponding manner to the press molds on thetable 24, and therefore a description of one of them should suffice forall. Referring first'to .the mechanism for bringing the glass blank fromthe press mold table to the blow mold table, 107 designates. a bottomformer-havinga plurality of ports 108 therethrough which communicatewith the interior ofthe tubular stem 109 to which the former isattached.This stem 109 is fixed toa bracket 110 of the member 111whichis-mounted-for slid-.

ing movement on an upright 112 carried by the table 28. The member 111is also provided with an'ear 113 by means of which itis fixed to thepiston rod 114 connected to piston 115 within cylinder 25. By thisconstruction the head 111 may be raisedor lowered, thereby carrying thebottom former 107 down through'an opening 116 in the table 28 intoengagement with the-blank in the press mold as shown. in Fig--20? .Thepressure fluid for operating'the piston 115 is conveyed by pipes 117 and118-to the respective ends of the cylinder 25, the said pipes beingconnected to a main control valve presently to be described.

, 119 designates a blow mold formed in sections each of which ispivotally mounted on the spindle 120., which latter is aflixed to anapertured plate 121 resting on the guide plate 122. This guide plate 122is provided with a central opening 123 and is slotted at each end asshown at 124 to receive the blocks 125 which connect by links 126 withEach block 125 carries a pin 127 fitting Within a cam groove 128 at eachside of the "cam plate 129, whichlatter is centrally apertured to form abearing on the central hub 130 of the guide plates 122. The care plate129 is pref erably moved in one direction by a pressure controlledmotor-.131 to which the pressure fluid is admitted at thedesired moment,and in the opposite'directionby a suitable tt'ip mechanism hereinafterdescribed.

132 designates the blow heads of which in the present instance there arefour, each beinto engagement with an ingsuitably pivoted at 133 to acylinder 25 so that they may be swung independently to aline with therespective blow mold openings. y

134 designates a lug or pin secured to each cam plate 129 andprojecting, through a suitable curved slot 135 in the table 28,

elongated opening 136 formed in the extension 137 of each blow head 132..By this construction movement of either the cam plates 129 causes thecorresponding blow head 132 to be swung either into or out of alinementwith a blow mold opening. In order to admit air to the blow mold heads132; a port 138 is formed in each havingcommunication by way of aflexible pipe or tube 139 with its adjacent to operate certain partshereinafter to be de scribed.

.Referring now to the main air control mechanism, attention is firstdirected to the fact that in my preferred construction, the column 2 isutilized as achamber for the exhaust from the several cylinders 25, and

it will be noted that its upper end adjacent the table 28 is providedwith a pair of channels 142 and 143 with which the air pressure pipes144 and 145 communicate respectively, the said pipes passing interiorlyof the column 2 and through a sleeve 146 whieh is secured, in thepresent instance, in a vacuum chamber 147.

l48gdesignates a plurality of exhaust ports formed in the column 1 2 andpreferably alined'with the inlet channel 142.

149 designates a second row of exhaust ports in the column 2 adjacentthe inlet channel 143. The two'channels 142 and 143 communicaterespectively with and are connected to the pipesv 144 and 145 by meansof the inlet ports 150 and 151.

152 designates a collar towhich the cylinder supply pipes 117 and 118are connected and through which they pass in order to formcommunications at certain times with the respectiveehannels 142 and 143and the exhaust-ports 148 ,and 149, it being under stood that'thiscollarfits over the column 2 and is seated upon the table 28, being retainedin this position by means of a retaining ring 153, which latter isfixedly secured to the column 2 by means'of set bolts 154, or likefastening devices. It will thus be apparent that as the table 28rotates, it carries the collar 152 with it and thereby successivelybrings the two pipes 117 and 118 into positionto receive air underpressure and operate one of the pistons in one of the cylinders for onemovement, and then as this pipe 117 is brought into position to exhaustby way of ports 148, a second pipe 118 will be receiving air. underpressure from channel 143, and it in turn will exhaust through the ports149 as the collar 152 continues its movement.

The vacuum chamber 147 communicates by way of the ports 155 in thesleeve 146 with the interior thereof, and it will here be understoodthat this sleeve is closed. at its inner end and is connected by meansof to lette I I i 6 f the ipe 156 within suitable suction device. aswill be understood.

In explaining the operation of the machine, the several steps in theformation of a single bottle will be followed, as it will be understoodthat each unit of the machine performs its functions independently, andin the present machine, four operations are going on simultaneously,thus one unit is cutting and punching one bottle blank; another unit isforming an initial opening in a second blank; another unit is blowing athird blank, while another unit is discharging a completed bottle.

The drivmg annulus 8'is first connected with the source of power andtherefore the two tables 24 and 28 and column 2 are ready admit air tothe to rotate as soon as the latch 74 releases them, since of course thefriction member 12 is contacting with the annulus 8 and tending torotate.

With the parts in the' position shown in Fig. 12, the operator drops agather of glass into the opening of the press mold 38 and at the sametime presses the treadle 80 until, it is held by the latch 83. Theposition of the press mold at this time is such that the suction head 98connects with port 44 and the glass is therefore drawn quickly intoplace. The lowering of the treadle 80 causes the three way valve 79 toturn to cylinders 72 and 88, the former shifting the cross head and thelatter operating the cutters 95 which sever the glass close to the topof the press mold. The downward movement of the cross head 70withdrawsthe latch bar 74 and cuts off the suction from head 98. Thetable 24 is therefore released and turns through approximatelyone-eighth of a revolution. 'At this point the crosshead 70 has loweredfar enough to allow the spring 75 to return .the

latch bar 74 so that it engages the next notch 76 and again locks thetable 24. Furthermore, the piston 71 has at this time struck the pin 86to release the treadle 80 and the return movement of this member underthe 4 influence of spring 82 again shifts the three way valve 79 andcauses air to be delivered to the blow head 101, which in the meantimesaid former.

It is now time has been brought up to port 44 through the operation ofmotor 104. The press mold 38 in passing from its initial position tothisone eight-h position has; passed over the cam 48 and the plunger 42 hasbeen forced upwardly to form a preliminary opening in the blank.

, Referring now' to the upper table 28, .the step of lowering one of thebottom formers 107 has taken place while the foregoing operations havebeen effected. The collar 152 has rotated one-eight of a turn andbrought pipe 117 into communication with the port 142, thus admittingair to one, cylinder 25 and causing piston 115 to lower and bring thesaid former .107 into contact with the glass blank as illustrated inFig. 20. It is in this position that air is admitted through port 44 toblow the opening 67 and press the blank firmly on the former 117,'whereit is held secure by the vacuum produced in the Afterthis step,the table 24 is automatically released, by the upward movement of crosshead 70, which of coursefollows from the valve 79 having been shifted bythe disengagement of latch 83 as heretofore described, and thereuponmoves another eighth turn, brifrgingthe blank to station B. At thisstation the press mold 38 is automatically opened by" 'th'e engagementof the lug 60- with the stationary trip. 61. for the bottom former 107to conveythe blank to thfblow mold table 28. The collar 152 is thereforein position to exhaust the upper end of" cylinder 25 through ports 14Sand admit air to the lower end by way of ports 143: and pipe 118 so thatthe former 107 moves upwardly carrying the blank into position withinthe blow mold 119 at station B. The movement of the table 28 from thestation B brings the nipple 188 in collar 152 into alinement with port185 so that the motor 131 is operated to close the mold about the blankand when station C is reached, the blow head 132 is positioned as shownin Fig. 11 and air enters the. blank and blows the complete bottle. Fromstation C the blow mold moves to station D where port 185 alines withexhaust port 192 and port 186 alines with inlet 191 so that motor 131 isagain operated, but in the reverse direction and the blow mold isopened. As soon as the mold opens, the

.vacuum ejector arm, 160 swings up automatically and grips the bottlewhich it then removes and delivers to a suitable point. As this ejectorvaction has already been described in detail it is thought unnecessary tohere repeat the several movements.

It will nowbe apparent that I have devised a' complete unitary structurewell adapted for the purpose intended and which is simple inconstruction, positive in operation and automatically carries out aseries of steps, one following another, and all coneases in-Hing in acomplete cycle which begins [with a gather of molten glass and ends witha completed article delivered to' a suitable int. 4 It will now beapparent that I have de vised a novel and. useful construction of anautomatic bottle blowing machine which embodies the features ofadvantage enumerated as desirable in the statement of the invention andthe above description, and while I have, in the present instance, shownand described a preferred embodiment thereof which has been found inpractice to give satisfactory and reliable results, itis to beunderstood that the same is susceptible of modification in variousparticulars without departing from the spirit or scope of thein ventionor sacrificing any of its advantages.

Having thus described. my invention, what I claim as new-and desire. tosecure by Lettors Patent, is
